| 摘 要： | 按小麦产量构成因素全因果关系通径模型,计算出因素对产量的总效应和总决定程度,通过比较决策出主攻因素。足水肥高产地和稻茬旋耕撒播两种生态条件下主攻因素为穗粒数,限水低肥地应主攻粒重,砂性漏水地的主攻因素为穗数。

| Abstract: | According to the path modle of causality within the compositive factors of wheat yield,the main factor could be decided through calculating and comparing the total effects and the total level decided of every factor to yield.On the condition, higher level of the soil fertility with plenty water and fertilizer, and wheat planted after rice by rotary tillage and broadcast sowing,the main factor was kernel number per spike.On the condition of less water and fertilizer, the main factor was kernel weight. On the condition of sandy and leaking soil, the main factor was spike number. |
